Microbiological Characteristics of Acute Prostatitis After Transrectal Prostate Biopsy

چکیده
PURPOSE We aimed to identify microbiological characteristics in patients with acute prostatitis after transrectal prostate biopsy to provide guidance in the review of prevention and treatment protocols. MATERIALS AND METHODS A retrospective analysis of medical records was performed in 1,814 cases who underwent prostate biopsy at Seoul St. Mary's Hospital and St. Vincent's Hospital over a 5 year period from 2006 to 2011. Cases in which acute prostatitis occurred within 7 days after the biopsy were investigated. Before starting treatment with antibiotics, sample collections were done for culture of urine and blood. Culture and drug susceptibility was identified by use of a method established by the Clinical and Laboratory Standards Institute. RESULTS A total of 1,814 biopsy procedures were performed in 1,541 patients. For 1,246 patients, the procedure was the first biopsy, whereas for 295 patients it was a repeat biopsy. Twenty-one patients (1.36%) were identified as having acute bacterial prostatitis after the biopsy. Fifteen patients (1.2%) had acute prostatitis after the first biopsy, and 6 patients (2.03%) experienced acute prostatitis after a repeat biopsy. Even though the incidence of acute bacterial prostatitis was higher after repeat biopsy than that after the first biopsy, there was no statistically significant intergroup difference in terms of incidence (χ(2)=1.223, p=0.269). When the collected urine and blood samples were cultured, Escherichia coli was found in samples from 15 patients (71.4%), Klebsiella pneumoniae in 3 patients (14.3%), Enterobacter intermedius in 1 patient (4.8%), E. aerogenes in 1 patient (4.8%), and Pseudomonas aeruginosa in 1 patient (4.8%). A fluoroquinolone-resistant strain was confirmed in 5 cases (23.8%) in total. Three cases of E. coli and 1 case of Klebsiella had extended-spectrum β-lactamase activity. CONCLUSIONS Empirical treatment of acute prostatitis should be done with consideration of geographical prevalence and drug resistance. This study will provide meaningful information for the management of acute prostatitis after transrectal prostate biopsy.

BACKGROUND Prevalence of fluoroquinolone (FQ)-resistant Escherichia coli has been recently increasing worldwide. We analyzed the incidence and characteristics of acute bacterial prostatitis after transrectal ultrasound-guided needle prostate biopsy (TRUSP-Bx) with prophylactic tazobactam/piperacillin (TAZ/PIPC) treatment as an alternative regimen. METHODS A total of 391 patients who underwent...
متن کاملAcute Bacterial Prostatitis: Diagnosis and Management.
Acute bacterial prostatitis is an acute infection of the prostate gland that causes pelvic pain and urinary tract symptoms, such as dysuria, urinary frequency, and urinary retention, and may lead to systemic symptoms, such as fevers, chills, nausea, emesis, and malaise. Although the true incidence is unknown, acute bacterial prostatitis is estimated to comprise approximately 10% of all cases of...

Background and Objective: Non-specific granulomatous prostatitis is an uncommon diffuse inflammatory condition of the prostate. It is important because it may be mistaken for prostatic carcinoma. The aim of the study was to determine the prevalence of non-specific granulomatous prostatitis (NSGP) and comparing the results of transrectal ultrasonography, serum prostate specific antigen (PSA) ...
متن کاملDoes a previous prostate biopsy-related acute bacterial prostatitis affect the results of radical prostatectomy?
OBJECTIVE To The standard technique for obtaining a histologic diagnosis of prostatic carcinomas is transrectal ultrasound guided prostate biopsy. Acute prostatitis which might develop after prostate biopsy can cause periprostatic inflammation and fibrosis. In this study, we performed a retrospective review of our database to determine whether ABP history might affect the outcome of RP. MATER...
